CAN-HEAD-FLANGE CURLING A ND COATING MACHINE.

Specification of Letters Patent.

Patented Sept. '7, 1915..

Application filed December 2, 1909. Serial No. 530,921.

To all whom. it may concern: I

Be it known that I, WILLIAM F. BUTLER,

a citizen of the United States, residing in Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Can-Head-Flange Curling and Coating Machines, of which the following is a specification.

My invention relates to the manufacture of 'can heads or covers of the. kind intended to be secured to the can body without solder and simply by double seaming.

Heretofore in the manufacture of can heads or covers for double seaming to can bodies, it has been customary after the can 1 heads or covers are stamped up or formed by the dies of the press and discharged into a basket or other receptacle, to first put them into a flange curling machine for curling the horizontal flange of the head to form a channel to receive the liquid cement or other packing, after i hich they are delivered to a coating machine which applies the cement or packing material to the flange of the cover.

in the channel formed by the flange curling machine. After the can heads have been cut and formed by the press, they frequently tend to stick or nest together, and it is a matter of considerable labor and difficulty to separate them and feed them to the flange eluding/machine, especially as the raw cut edges of the seaming flanges tend to cut or wear and injure the fingers in handling.

.The object of my invention is to provide a combined machine of. a. simple, efiicient and durable construction which will automatically stamp up or form the can heads or covers, curl the flanges thereof and apply the cement or packing thereto.

My invention consists in connection with a press having can head cutting and formins! .dies, a can head conveyer to which the can heads are. delivered one by one as they are out and formed by the press, a continuouslv rotating can head feeder having a plurality of can head receiving pockets or guides to which the. can heads are delivered bv said conveyer as they are formed by the press, a ,ontinuously rotating can head carrier having a plurality ofpairs of rotary can head holders or clamping chucks between which the can heads are delivered one by one by said feeder, a plurality of flange curling tools or rollers preferably carried. by radially reclprocating slides on said carrier,

a cement tank or receptacle mounted on said carrier and rotating therewith, and provided with a series of feed pumps, controlment or packing composition, means for controlling the operation of the controlling valves by the presence or absence of a can head in the holders, a stirrer for the cement or packing composition in the tank, stationary cams and connections for operating the can head holders to clamp and unclamp the can heads as the carrier rotates and gearing for axially rotating the can head holders and operating the pumps and controlling valves as the carrier rotates.

My invention also consists in the novel construction of parts and devices and in the novel combinations and sub combinations of parts and devices herein shown and described and more particularly specified in the claims.

In'the accompanying drawing forming a part of this specification, Figure 1 is a plan view of a machine embodying my invention, the can head cutting and forming press being only conventionally indicated. Fig. 2 is a central, vertical section on line 22 of Fig.

v1. Fig. 3 is an elevation, partly in section on' line 33 of Fig. 1. Figs. 4 and 5 are detail sections on lines 44 and 55 of Fig.

2 respectively. Fig. 6 is an enlarged detail plan view, partly in horizontal section, showing one of the controlling valves for one of the feed pumps. Fig. 7 is a. detail vertical section on line 77 of Fig. 6. Fig. 8 is an enlarged elevation, partly in vertical section, showing one of the discharge nozzles and its feed pump and controlling valve.

the machine, 2 a press of'any suitable kind or construction having can head cutting and forming dies 3, 4, and discharge chute 5 which delivers the can heads as they are formed to a can head conveyor 6 preferabl an endless flexible conveyer having fingers.

to engage the can heads, said conveyer opcrating to move the can heads one by'one'. onto a stationary feed table or plate,8 having a slot 10 for the fingers 7 of the-conveyer 6 and deliver them one by one into'the' pockets or converging guides 11 of the con-=3 tinuously rotating can headfeeder 12,;whioh erably adjustably secured to thecarrier 12.

by bolts 17 which pass through slots 18in the pockets or guides 11' so that they may be adjusted radially in or out to accommodate ,pre'f erably continuously rotated from the can heads or covers of different diameters.

The can head carrier 16 rotates continuously in conjunction with, the can-head feeder 12,- and, it is provided preferablywith six pairs of axially rotatingcam head holders or clamping chucks 14, 15,01 one pair for each of the canhead pockets 11 on the feeder 12-.- One offthe can head holders or clamping chucks 14, 15 of each pair is adapted to be reciprocated to and from the other to clamp-and unclamp the can head between them. The .lower holder or chuck 15 is preferablythe reciprocating one, and it is preferably reciprocated as required to clamp and unclamp the can head by means of a stationary cam 19 on the frame of the machine, in which engages a roller 20 on a lever 21 hinged to a bracket or' arm 22 on the carrier 16, and which lever '21 engagesthe rounded end or head 23 of the spindle 24 of the lower clamp chuck 15. One of the rotatable can head holders 14, 15, preferably the lower one, is' driven, this being preferably done by spur gears 25 onthe spindles 24- which mesh with a stationary gear 26 on'the frame of the machine.

The upper clamping chucks or holders 14 are preferably furnished with hollow shafts 0 or sleeves 27 which are mouritedto rotate." in suitable bearings or bars 28 secured to the continuously rotating can head carrier, 16. Each pair of upper and lower can head holders or clamping chucks 14, 15 is shaped to conform to the central portionv of the can head 29 so as to leave the flange 30 of the can head projectingbeyond the periph-' cry of the clamp chucks to enable said flange to beiturned' upward at-its outer edge to form the curl 31, and als to enable the channel thus formed the can head flange to receive its coatiiig 33 of liquid cement or packing composition, and to enonto the can head flange. .1

able the can head holder chucks to coiiperate ,with' the discharge. or distributing] e fiee nozzle which feedsv the packing The carrier 16 is provl carriedby'a-radially movableslide'35. flanging; or roller 34i-is rotatably nected to its slide'or holder-"35 "by 233110111" shaft. or pin' 36. Each ofEthe radial slides '35 moves'in suitable radial guides on the carrier 16. The Hanging roller slides 35am preferably reciprocated as required toj'causo' the flanging rollers to engage the flange 80 of the can head 29' and form the curl 31 on its-outer edge, by means of a stationary cam 3 6 on the frame of the machine which is engaged by a roller 37 onthe'fianging tool operating lever 38, the upper end' of which engages the. slide 35 and which is fulcrumedat 39 on a' bracket 40 on the carrier 16.

The horizontally rotating carrier 16 is driving shaft 41 through bevel gears 42, 43, the latter being on theupright shaft 44, having a spur gear-45 which meshes with a gear 46 onthe shaft 47 of the carrier 16. n

bevel gear 51 on the shaft 52 of'the sprocket wheel 53 ofthe conveyer 6.

The liquid cement or packing composition is contained in a rotary tank or receptacle 54, which is preferably adjustably connected to the carrier 16 so as to rotate therewith by means of connecting brackets 55 having slots 56' to receive the bolts 57 and jaws 58 embracing the upwardly projecting rib 59 of the arms 28 on the carrier 16. The tank or receptacle 54 is preferably furnished with a stationary stirrer 60 preferably in the form of a screw blade and supported by a' stem 61 attached to the frame of the machine, the stem 61 extending through the cover 62 of the tank 54. The cement tank or receptacle 54 is provided with a plurality of cement discharging or distributing nozzles 63, one for each pair of can head holders '14, 15, each nozzle communicating with the interior o f the tank 54 through a. communicating passage or'port 64 and an interposed feed pump and controlling valve.

The shell or cylinder 96 of each feed pump is preferably secured to the tank 54 by bolts and its piston 66, which is preferably a cement or packing composition upon each l, aeewim t nsof r dm em e e w l jstools 1 rollers-34', each preferably mounted on or;

preferably by means of a stationary cam ":67 on'the frame of the machine which is engaged by a roller 68 on a lever 69, pivoted to a bracket 70 on the rotating "carrier 16 or its tank 54 whichrotates therewith, and which lever 69 is pivotally connected with the stem 71 of the piston.

The controlling valve 72 is preferably a reciprocating one and has a port 73 adapted to register with the ports 7 4, 75 of the valve shell, which is preferably integral with the pump cylinder or shell, and is reciprocated as required to open and close' the valve,

through an interposed spring 76, by a stationary cam 77 on the frame of the machine,

, which is engaged by a roller 7 8 on a lever 79, pivoted to the rotary carrier 16 or its tank 54, and having an arm which is pivotally connected with the valve 72., The

' valve 72 has a return port or passage 80 to in the art, it is unnecessary to particularly permit the liquid to return to the chamber I of the-pump cylinder when the pump piston makes a stroke while the controlling valve is not open. The,-.controlling valve 72 has a notch or projection '81 adapted to be engaged by a controlling device or movable trigger 82, the trigger or controlling device 82being normally held out of engagement with the valve 7 2, as shown in Fig. 8 whenever a can head is present in the axially rotatable holders 14, 15 of the carrier to receive the charge of cement or packing composition. When no can head is present onthe holders 14, 15, thetrigger 82 will drop intoposition to lock-the valve 72 from movement and the roller 7 8 on the lever 79 will be retained in itsuppermost position, or in other words, in engagement with the upper if one is present in the holders 14, 15, thus raising the pin and causing it in turn to raise w the trigger or valve-controlling device 82.

The stationary cam 67 is preferably composed of flexible rails, as shown in Fig. 9.. so that the same may be adjusted up or ,down to regulate the stroke of the feed piston through the connecting strap 84 and 'adjusti-ngscrew 85.

As the construction and operation of can head or cover cutting and forming presses and their dies is wellkriown to those skilled show or describe the same.

After the can heads have been operated discharge chute .87. e

heads on the carrier which engages and frees the can heads from the lower 1 can head holder chucks and delivers them into the The lower can head holder chucks 15 are moved upward by the operation of the stationary cam 19-just as each can head pocket 11 on the feeder 12 comes radially opposite the can head holder 15 on the carrier-l6, the chuck disk 15 thus lifting the can head above the converging guides or pockets 11 of the feeder and thereby transferring each can head from the continuously rotating feeder 12 to the continuously rotating carrier 1-6.

Hand operated valves 88 arepreferably provided. for closing the passages 64 when desired for repairs orother purposes.
